Using Search Hedges in PubMed

Search hedges, sometimes called search filters, are designed to narrow your results based on specific criteria, such as publication type. They are designed by experts to be as comprehensive as possible.

Watch the video below to learn how to use a search hedge, specifically the CADTH hedge which limits to systematic reviews and other evidence syntheses.

You can find the full hedge to copy and paste into your PubMed search in the next box on this page. Don't forget to acknowledge and cite any hedges you use in your searches!

Common Search Hedges & How to Find Others

Below is the CADTH search hedge to limit to systematic reviews and other evidence syntheses in PubMed. To use this, as with most search hedges, follow these steps:

  1. Do a search for the full text of the hedge in the PubMed Advanced Search query box.
  2. Use AND to combine the results of the search hedge with the search or searches that reflect the concepts in your research question.

You can copy and paste the text below to execute the first step above.

In future searches, you may need additional search hedges. These are my most-used sources of hedges, although they're certainly not the only place to find them.
